Abstract

TITRE : MODULE DE SOUFFLANTE COMPRENANT DES MOYENS D’ETANCHEITE AMELIORES D’UNE ENCEINTE DE LUBRIFIANT L’invention concerne un module de soufflante (10) de turbomachine comprenant un arbre de soufflante (5) et une enceinte (8) de lubrification traversée axialement par au moins une partie de l’arbre de soufflante et comportant au moins un premier palier (6, 7) destiné à porter et guider en rotation l’arbre de soufflante, l’arbre de soufflante comprenant une première partie tubulaire (5a) fermée par un couvercle (30), la première partie tubulaire comprenant une extrémité distale (23), une extrémité proximale (20) opposées suivant un axe longitudinale X et une baignoire (25) annulaire, ménagée dans une surface interne (24) de l’arbre de soufflante, entre l’extrémité distale et l’extrémité proximale. Selon l’invention, ledit couvercle comprend un corps (31) s’étendant suivant l’axe longitudinal X et monté dans la première portion tubulaire de sorte à couvrir et fermer de manière étanche la baignoire annulaire. Figure pour l’abrégé : Figure  2TITLE: FAN MODULE COMPRISING IMPROVED SEALING MEANS OF A LUBRICANT ENCLOSURE The invention relates to a turbine engine fan module (10) comprising a fan shaft (5) and a lubrication enclosure (8) through which at least a part of the fan shaft and comprising at least a first bearing (6, 7) intended to carry and guide the fan shaft in rotation, the fan shaft comprising a first tubular part (5a) closed by a cover (30), the first tubular part comprising a distal end (23), a proximal end (20) opposed along a longitudinal axis X and an annular tub (25), formed in an internal surface (24) of the shaft fan, between the distal end and the proximal end. According to the invention, said lid comprises a body (31) extending along the longitudinal axis X and mounted in the first tubular portion so as to cover and seal the annular bath.
